The DB11 doesn't need a big wing at the back because of this cool aerodynamic touch.

The Aston Martin DB11 is full of neat little design touches that combine to make the coupe a gorgeous grand tourer. Now a new video from the company highlights one of the most interesting details that also happens to be very well hidden – the AeroBlade.

This interesting aerodynamic aid reduces rear-end lift by creating a jet of disrupted air out the back. An intake at the base of each C-pillar channels sends the air out of a duct in the decklid. According to Aston Martin, the design allows the stylists to create the attractive sloping tail without the need of a small lip at the end, which would accomplish a similar result but spoil the handsome look. The picture below shows how the AeroBlade routes air from the side of the coupe and out of the rear.

The DB11 isn’t wing-free, though. At high speeds, a quite small active spoiler comes out of the decklid. When deployed, this tiny aerodynamic aid increases the effectiveness of the AeroBlade, and it can retract when the driver returns to lower velocities.

Aston Martin’s first teaser image of the DB11 Volante lacks (or at least hides) the AeroBlade’s intakes because there’re no longer fixed C-pillars. It’s possible the company could give the droptop variant slightly wider hips and build the aerodynamic aids into there.

The DB11 is on sale now and is the first model in Aston Martin’s “Second Century” product plan. It features the company’s new biturbo 5.2-liter V12 with 600 horsepower (447 kilowatts) and 516 pound-feet (700 Newton-meters) of torque that gets the coupe to 62 miles per hour (100 kilometers per hour) in 3.9 seconds. The model was an immediate hit with over 3,000 orders by the time production began in September. Aston Martin President and CEO promised to personally inspect the first 1,000 of them off the assembly line.
